In this book the research on atmospheric deposition of the Dutch Priority Programme on Acidification Research is summarised. Although most research described is of Dutch origin, it has been put into a broader perspective by outlining the state of knowledge on the process affecting atmospheric deposition in Europe. This has resulted in detailed deposition maps for the Netherlands and Europe. The volume is intended for those who measure or model atmospheric deposition and ecologists interested in exposure from atmospheric deposition, as well as policy-makers and students.
